Hatsune is a girl who grew up with five brothers, a father, and no mother. It is perhaps because of this that she developed a strange and unfortunate habit: every time she opens her mouth, something extremely rude comes out, even when she means to say something nice. For example, if she goes up to a person, intending to complement their shoes, she might say "Nice shoes, bitch. Where'd you get them? Garbage heap?" It's because of this that she hasn't had a boyfriend, or even a friend period, in all her life. Now Hatsune is trying desperately to break this bad habit and get a boyfriend, but when signing up for a club is mandatory at her school and she accidently insults her way out of every club her school has to offer save one, she has no choice but to join the school's "Maidens' Club", a club dedicated to making girls happy and that is run by a gay boy with an equally bad habit that kicks in every time a girl comes within one foot of him. The club has no "active" members except Hatsune and Kirie (the other club member). Soon Kirie is Hatsune's only friend, and with his help she hopes to gain more. But will she ever become more than just a friend to Kirie?
